I am in search of some practical (layman terms) help for fifth wheel chucking. I am relatively new to fifth wheeling and towing in general. I have a 29 ft fifth wheel with a 11,000 lb GVWR (older so...

The last two suggestions are good. Shocks on the trailer reduces the tendency of the trailer to rotate. Filling the water tank has two advantages; Causes the truck to squat a little more and reduces the hitch angle plus increases the polar moment of inertia reducing the rotation of the trailer. Higher quality axle equalization also reduces the tendency to rotate.
Towing nose high is a no-no as it increases the hitch angle. The greater the hitch angle, the more chucking forces relative to bouncing forces that are created by the trailer.
Another cheap but not advisable solution is to put on air bags and harden the rear axle of your truck. You would have to pump your pin box to the max. This would cause your trailer not to rotate and would reduce the chucking forces (fore-aft). The problem is the trailer is still generating the forces and they are now being absorbed by the frame plus all the truck generated forces are being transmitted to the trailer frame and its welds.
